Radical islam is the essence of islam. It won't be defeated by going after indivuduals, that's like trying to attack a field of grass by clipping a few of the tallest blades. It'll be defeated when allah is shown to muslims conclusively to be an impotetent faker.
Yes --- I agree with that --- going after the people --- either as a group or individuals isn't going to be that effective --- we'll have to do more than that --- Mecca at some point needs to be destroyed --- then they have nothing to bow down to and nothing to worship.
